The Linconn LC620 delivers a high-performance, compact solution for professional audio applications, combining push-pull quick-locking with professional-grade audio transmission fidelity. Its metal housing provides exceptional electromagnetic shielding, effectively suppressing RF interference. Gold-plated contacts ensure low contact resistance and corrosion resistance, making it suitable for transmitting weak microphone-level signals. Available in 3-pin (balanced) or 4-pin (with microphone) configurations, the push-pull locking mechanism facilitates operation on stage and equipment backplanes. Widely used in high-end microphones, in-ear monitoring systems, and broadcast camera audio channels.
